Both the first substrate 110 and the second substrate 120 may be glass plates, and the second substrate 120 may be provided with thin film transistors. The wiring structure 130 may be a ring structure, and the wiring structure 130 defines a first light through hole through which light can pass, so that light in the external environment can enter the camera module 200. The display module 100 may further include a light-emitting part 140, a transparent cover 150, an optical glue 160, a polarizer 170, and a foam 180. The light-emitting part 140 may be disposed between the first substrate 110 and the second substrate 120. The light-emitting part 140 may be an organic light-emitting layer; the polarizer 170 may be disposed on the surface of the first substrate 110 away from the second substrate 120; the light-transmitting cover 150 is located on the side of the first substrate 110 away from the second substrate 120, and transmits light The cover 150 can be connected to the polarizer 170 through the optical glue 160; the foam 180 can be arranged on the side of the second substrate 120 away from the first substrate 110, the foam 180 can be bonded to the second substrate 120, and can be provided on it. Avoidance hole, at least a part of the camera module 200 can be located in the avoidance hole, so as to prevent the stray light in the display module 100 from affecting the normal operation of the camera module 200, and at the same time, can reduce the space occupied by the camera module 200, thereby reducing The thickness of small electronic devices.

The camera module 200 may specifically include a camera body 210 and a light shielding layer 220. The camera body 210 is provided with a light inlet 211, the second substrate 120 is located between the first substrate 110 and the camera body 210, and the light shielding layer 220 is provided on the polarizer 170 away from the first On one side of the substrate 110, the light shielding layer 220 defines a second light through hole. The camera body 210 may specifically include a bracket 212, a lens assembly, and a photosensitive chip 213. The lens assembly is arranged on the bracket 212. The lens assembly may include lenses such as a convex lens and a concave lens to achieve the effect of light convergence. The photosensitive chip 213 may be arranged on the bracket. In 212, the photosensitive chip 213 has a photosensitive area for photosensitive, and the photosensitive chip 213 can convert light signals into electrical signals, thereby obtaining corresponding image information. The second light-passing hole here can also allow light to pass through, so that light from the external environment can enter the camera module 200 and reach the photosensitive area of the photosensitive chip 213, thereby realizing the shooting function.

The above-mentioned wiring structure 130 and the light-shielding layer 220 can both play a role of light-shielding. The above-mentioned first light through hole, second light through hole and light entrance hole 211 are arranged in the direction of the optical axis of the camera module 200, so the external environment The light in the light can pass through the second light-passing hole and the first light-passing hole in sequence, and finally enter the camera module 200 through the light inlet 211, so that the camera module 200 can realize the shooting function. The orthographic projection of the first light-passing hole on the surface perpendicular to the optical axis direction of the camera module 200 and the orthographic projection of the second light-passing hole on the surface perpendicular to the optical axis direction are both located at the light entrance hole 211 in the direction perpendicular to the optical axis. In the orthographic projection on the surface in the optical axis direction. That is to say, when viewed in the direction of the optical axis of the camera module 200, the outline size of the first light-passing hole and the outline size of the second light-passing hole are both smaller than the outline size of the light entrance hole 211. The size of the light inlet 211 is slightly larger, so that the setting will not affect the screen-to-body ratio of the display module 100, and can ensure that the light in the external environment enters the camera module 200 as much as possible. The first light-through hole and the second light-through hole will affect the screen-to-body ratio of the display module 100. Therefore, under the premise of meeting the shooting requirements of the camera module 200, the first light-through hole and the second light-through hole can be used as much as possible The light-passing hole is set to be smaller, so as to reduce the occupancy rate of the wiring structure 130 and the light shielding layer 220 to the display area, and achieve the purpose of increasing the screen-to-body ratio of the electronic device.

In the above electronic device, the light shielding layer 220 of the camera module 200 is disposed on the display module 100. This design makes the distance between the light shielding layer 220 and the display module 100 almost zero on the one hand, so the first light through hole can be more On the other hand, there is no assembly error between the display module 100 and the light-shielding layer 220, so there is no need to consider the assembly error when opening the first light-through hole. The size of the first light-through hole can be further reduced, so that the electronic device The screen-to-body ratio is higher. At the same time, after the size of the first light through hole is reduced, the appearance and texture of the electronic device are improved, and the user experience is also improved.

In an optional embodiment, the polarizer 170 is provided with a third light-passing hole, which allows light to pass through, thereby increasing the light transmittance of the area corresponding to the camera module 200, thereby improving the camera module. The shooting quality of group 200. The orthographic projection of the third light-passing hole on the surface perpendicular to the aforementioned optical axis direction coincides with the orthographic projection of the second light-passing hole on the surface perpendicular to the optical axis direction. At this time, a part of the optical glue 160 can extend into the third light-passing hole and the second light-passing hole, so as to fill the third light-passing hole and the second light-passing hole. Therefore, this part of the optical glue 160 can be connected to the first light-passing hole. The surface of the substrate 110 facing away from the second substrate 120 is in contact with the first substrate 110, so that the structural strength of the display module 100 is higher. More importantly, in the process of processing the display module 100, the positions of the light shielding layer 220 and the polarizer 170 can be referred to each other, so as to facilitate rapid prototyping of the display module 100 and improve the molding efficiency of the display module; The edge formed after the polarizer 170 is opened with the third light-through hole is aligned with the edge formed after the light-shielding layer 220 is opened with the second light-through hole. On the one hand, the molding quality of the light-shielding layer 220 can be ensured, and on the other hand, the light-shielding layer can be made 220 is as close as possible to the center line of the third through hole, so as to reduce the size of the light-shielding layer 220, so that the cost of the light-shielding layer 220 is lower, and at the same time, it can prevent the size of the light-shielding layer 220 from being too large and making the display module 100 unusable. The display area increases, thereby increasing the screen-to-body ratio of the electronic device.

As mentioned above, the first light-through hole and the second light-through hole will affect the screen-to-body ratio of the display module 100, so the first light-through hole and the second light-through hole can be set as small as possible. In an optional embodiment, the orthographic projection of the first light-passing hole on the surface perpendicular to the optical axis direction of the camera module 200 and the orthographic projection of the second light-passing hole on the surface perpendicular to the optical axis direction Can overlap. In other words, the shape of the first light-passing hole and the shape of the second light-passing hole are the same, and the sizes of the two are the same. This arrangement can make the size of the first light-passing hole and the second light-passing hole as small as possible. At the same time, the relative positions of the two can be referred to each other when the display module 100 is formed, thereby making it easier to process the display module 100.

In the embodiment of the present disclosure, the outer contour shape of the wiring structure 130 and the light shielding layer 220 can be flexibly set. For example, the outer contour shape can be a rectangle, a circle, or an ellipse. At the same time, the first light-through hole and the second light-through hole The shape of the can also be flexibly selected, for example, rectangular holes, round holes, oval holes and so on. In an alternative embodiment, considering that the shape of the field of view of the camera module 200 is generally circular, in order to adapt the camera module 200 to further increase the screen-to-body ratio of the electronic device, the wiring structure 130 and The light-shielding layers 220 are all arranged in a circular ring structure. At this time, the radial width of the light-shielding layer 220 can be smaller than the radial width of the wiring structure 130, so as to prevent the radial width of the light-shielding layer 220 from being too large and causing the light-shielding area to be too large. , And then achieve the aforementioned purpose.

As shown in Figure 1, H=A+D*2, where: H is the size of the hole that cannot be used for display on the appearance surface of the display module 100, and A is the aperture of the second light-passing hole (or the first pass) The aperture of the light hole), and D is the width of the wiring structure 130. Since the field of view β of the camera module 200 is a constant value, A is basically a constant value, and D is also a basically constant value. At this time, the size of H is not affected by factors such as assembly errors, so H can be set smaller.

In order to improve the shooting effect of the camera module 200, the distance between the focal point of the camera body 210 and the light shielding layer 220 in the aforementioned optical axis direction may be a preset value. In other words, when the position of the light shielding layer 220 changes, the position of the camera body 210 changes accordingly to ensure that the focal point of the camera body 210 and the light shielding layer 220 maintain a matching position, thereby achieving the purpose of improving the shooting effect. In the embodiment of the present disclosure, since the light shielding layer 220 is moved up to the display module 100, the distance between the camera body 210 and the display module 100 can be further reduced, making the distribution of the display module 100 and the camera module 200 more compact , Which is more conducive to the stacking of components in electronic equipment.

There are various implementations for forming the light-shielding layer 220. In an optional embodiment, the light-shielding layer 220 can be formed by a coating process, that is, the light-shielding layer 220 can be a coating structure, which is easy to form. In addition, the thickness of the formed light shielding layer 220 is small, which is more beneficial to control the thickness of the electronic device.

Of course, the light shielding layer 220 may also be a printed structure. That is, the light-shielding layer 220 can be formed on the side of the polarizer 170 away from the first substrate 110 by a printing process. This method also has the advantages of being easy to implement and the thickness of the light-shielding layer 220 formed is small.

When assembling electronic equipment, the alignment and fixation between the light shielding layer 220 and the camera body 210 can be achieved through the precise positioning of the charge-coupled device (CCD) camera and the dynamic adjustment and alignment of the micro-motor-driven camera module 200. Therefore, the relative position accuracy of the light-shielding layer 220 and the camera body 210 is higher, which not only ensures the imaging effect of the camera module 200, but also increases the size of the first light-passing hole without considering the alignment error, thereby improving the performance of the electronic device. Screen-to-body ratio.

The electronic device disclosed in the embodiment of the present disclosure may be a smart phone, a tablet computer, an e-book reader, or a wearable device. Of course, the electronic device may also be other devices, which is not limited in the embodiments of the present disclosure.
